BINDING POST FOR CALENDARS.

Application filed April 17, 1922. Serial No. 553,550.

To all whom it may concern:

Be it known that I, \VILLIAM T. Suniiviiiv, a citizen of the United States of America, and resident of Cincinnati, in the county of Hamilton and State of Ohio, have in vented a new and useful Improvement in a Binding Post for Calendars, of which the following is a specification.

An object of my invention is to provide a simple and eflicient binding post for calendar pads and pads of a like and similar nature.

Another object of my invention is to provide a binding post which will not sag or become wobbly on its base or retaining means because of the removal of sheets of paper therefrom.

These and other objects are obtained by means described herein and disclosed in the accompanying drawing, in which:

Fig. l is'a perspective view of a calendar pad having mounted on it binding posts embodying my invention.

Fig. 2 is a fragmental perspective view of a binding post embodying my invention, mounted on a calendar pad.

Fig. 3 is an enlarged sectional view on line 33 of Fig. 2.

The post of my invention comprises a screw 4 having a head 5 and a threaded shank 6 upon which may be mounted a sleeve or tube 7 having an annular flange 8 at one end. The shank of the screw is longer than the sleeve. and is adapted to have mounted on it the sleeve 7, and to extend thru the back or base 9 of a pad 10 and to have secured upon it a nut 11.

iy referring to 8 it is apparent that when the sheets 12 comprising the pad of the calendar are assembled on the sleeve 7, and the screw 4 is inserted through the Are sleeve so as to space the flange 8 from the head 41: of the screw, and the threaded end of the screw is inserted thru the perforations 13 in the pad 10, the nut 11 may be mounted upon the threaded end. of the screw whereby to clamp the base 9 between the flange 8 and the nut. It should be further observed that the end of the sleeve which engages the head of the screw cooperates in effecting this clamping action in that the head of the screw limits the relative move ment of the sleeve and screw, and therefore determines the position which the post assumes in relation to the base. It should be further observed that the post serves to retain loose sheets or leaves, which leaves may be removed from the post without leaving any scrub upon the post.

What I claim is.

In a calendar pad and the like the combination of a perforated base, a pad of sheets each having a perforation aligned with the perforation in the base, a sleeve having a radial flange at one end received in the perforations in the sheets. and having the flange interposed between the sheets and the base, a headed screw extending through the sleeve and the base, the head being spaced by the sleeve from the base and serving as an abutment for retaining the sheets on the sleeve and serving as an abutment for engagement of the sheets for individually tearing the sheets from the perforations therein for separating the individual sheets from the sleeve, and a nut at the back of the base, receiving the screw and clamping the base between the flange and the nut.

In testimony whereof, I have hereunto subscribed my name this 14th day of April, 1922.

WILLIAM T. SULLIVAN.
